ABSTRACT
We surgically treated a case of anomalous origin of the left coronary artery from the pulmonary artery with the specific route of the left coronary artery in a 17-month-old boy. He had suffered persistent cough and poor weight gain since the age of 4 months. An ultrasound cardiography, at the age of 16 months, revealed retrograde blood flow of the left coronary artery into the main pulmonary artery. Moreover, a chest computed tomography showed an anomalous left coronary artery arising from the bifurcation of the right pulmonary artery and winding in contact on the posterior aortic wall. Though the anomalous left coronary artery shared adventitia with the aortic wall we were able to separate the coronary artery from the aorta, and the patient underwent direct transplantation of the left coronary artery. The postoperative course was uneventful and recovery was rapid.
